This is a trait I was rather pleasantly surprised to observe

From a very early age, Dev enjoyed the company of family and friends.
Infact he loves to be surrounded by people and thats his fun-time.
He would sometimes run to a stranger and hand her over a flower to say "Hello !".
When I chide him to be cautious, he would smile and say, "She is MY Oma" - meaning grandmother in German.
Thats one of his interest areas (I think), he likes to travel to new places where he can interact with people!
He collects new shapes of leaves and flowers to gift them to those old ladies and enjoy seeing smiles on their faces. These strangers are mostly elderly people or small babies.
In his kindergarten(3 yrs), once the manager told us that, he loves visiting old age homes and sing for them! He has a natural liking to "serve", either by help feeding babies in his kindergarten or holding the hand of an old lady crossing the road, that was few days back here(in Switzerland). I'm not sure though if he understands what "serve" means, but the joy I see on his face after the act is so pleasurable!
